Dual Motor Kit for Currie Scooters

I want to convert my GT Scooter to a dual motor configuration. I'm having a hard time finding a kit. Only two places on-line that I have found them for sale: EVDeals (which is out of stock) and TheSuperKids which does not respond to my e-mails or voice messages.

Anyone know of another source for this kit?

Thanks,

Harlow

You might check with Powerpack Motors.

With an upgraded controller, the BMC motor will easily do 1500w, possibly making a dual motor unnecessary.

Re: Dual Motor Kit for Currie Scooters

I had a phone conversation with Tim from PowerPack yesterday. He has no Dual-Kits and is not planning another production run in the foreseeable future.

My existing 2 options are:

Find a used plate - anyone have one for sale?

Make my own - Don't want to spend the time.

OR:

Forget the whole dual motor thing and find one good motor that will give me strong acceleration.

Which BMC motor are you referring to? 1500W?
Do you recommend a specific controller for that?

Thanks.

Re: Dual Motor Kit for Currie Scooters

We got Tim's last adapter plate and just got done setting up a twin motor Schwinn Missle. We made a drawing of it so we could make another if needed. I think what has happened is that all the current Currie scooters are direct drive, so the interest in hopping up the older chain drive stuff has gone down. EV deals stopped carrying a lot of the neat stuff he used to supply for those scooters, including a great disc brake kit for the rear.

the main benefit of the twin motors is acceleration. Even with some moderate power 400 watt Kollmorgan motors run at 24V, the thing takes off like a rocket. By the way, we run a Watts Up meter, and the 2 Kollmorgons hit 2034 watts peak and drew over 100 amps peak combined output! The scooter will do about 20 mph top end with 19mm front sprocket, but climbs really well. Twin 600 watt motors would probably hit close to 30 MPH with the same gearing, and we are thinking about it as an option. Boy those Kollmorgan 400 watt brushless motors are smooth and quiet though.

It is a more complicated set up to get right than one single motor, and will drain batteries pretty fast. if you try to run both motors off the same battery pack, you need 6 or 8 gauge wire, and Anderson 100 amp connectors, and a 75 amp switch and fuse. We melted a bunch of connectors and ruined a pretty heavy duty switch, and blew a 40 amp fuse too. We ended up running two seperate 24 volt battery packs and two switches, two 50 amp fuses, and with two charger ports. That way the system amps are kept to below 50.

Getting the chain just right with twin motors is more finicky as well. We had to slot the axle hole on the adapter plate. A flat on the back tire would be even more of a nuisance to fix.

I run a single Powerpack motor from Tim on my Lashout with a 48 volt 20AH LIFEPO4 pack. It out performs the twin engine 24 volt 400 watt X 2 set up except in initial acceleration, and would probably give a twin 600 watt motor a run for its money. My top end is over 30 mph on flat ground, and I can go 20 MPH up a 10% grade. Its a great deal for about $300 for the kit and is an easy install.

here is the motor I am talking about. It puts out about 1500 watts peak, 850 watts continuous with the 35 amp 48 volt controller it comes with.

Re: Dual Motor Kit for Currie Scooters

Thanks for the set-up tips. Seems like two completely separate 24V systems is the way to go.

So each motor is switched so you can run each independently or both together? I thought HiKols drew around 30A. Over 50, huh? What kind of range can you get? I can see a lot of jack-rabbit starts could have an affect on run time. Bet they're fun though!

I'd be interested in knowing what Ah batts you had in there.

btw, there is a pair of Kollmorgen 400W Brushless on e-bay right now. Brand new in original packing. $69.99 + $14.50 Ship.

Re: Dual Motor Kit for Currie Scooters

Hi,
In answer to your question: The dual 400w Hi-kols on the 'Missile' are pulling 48.96 'peak' amps on the watts-up meter. The continuous amps are 23-35. The setup is 2 separate 24 volt x 12ah battery paks (with separate charging ports) and the range/distance per charge with some 8-12% hill climbing included is @ 5.25 miles....that's with a 240 lb rider.
The duals pull up the hills (19T sprockets)beautifully at @ 10-12mph; but the top end on level ground is only 19.5 mph. * working on increasing the top speed(while keep hill climbing ability) and adding more distance per charge.
Hope this helps answer you questions........Have a good day!

Re: Dual Motor Kit for Currie Scooters

. I have one of the 1500 watt brushless motors Tim sold me and I have been running it for about 14 months. I cannot say enough good things about the motor. I am currently testing a modified controller with big fets which I believe is rated at 75-80 amps. I just (last night) modified my battery pan so I was able to fit 4 22ah batteries. I had a 55 amp controller before and it worked well with the big batteries and consistantly ran hard 36-38* mph. If your interested, I'll post a new photo of it. It's a modified I-Zip 1000. I am running 60:19 gear ratio and if geared it any lower, I would need a wheelie bar. I'm not kidding. The motor is flat out wild. Kudos to Tim for all his dilegence and cost effective products.

Re: Dual Motor Kit for Currie Scooters

Yes, please post some pics. I have a Schwinn Stealth 1000 and want to go to 48V. I have one of Tim's PowerPack motors and controllers. It's supposed to be 35A. When I tossed-out the original 10Ah batts, I replaced with (3) 17Ah. I was able to lay (2) on their side under the deck, and I hung the 3rd on the back of the seat post. I'd be interested to see how you put (4) 12V 22Ah batts in your I-Zip. Thanks.
